See 'Fantastic Four' Rise to Power in Epic New Trailer

Superheroes fend off government agents, Dr. Doom in upcoming reboot

The latest trailer for Marvel and Fox's Fantastic Four reboot opens not with an origin story but a pre-origin story: Long before he was Mr. Fantastic, Reed Richards was like any other normal kid, bragging about his teleportation device in class and causing massive blackouts in his neighborhood with botched science experiments.

"Reed, you're insane," his friend remarks while staring at the wunderkind's smoking machine. "Thanks," says the superhero-to-be.

The new clip goes on to showcase the Fantastic Four's actual ground-zero moment — a freak accident in an alternate universe that leaves Reed (Miles Teller), Johnny Storm (Michael B. Jordan), Sue Storm (Kate Mara) and Ben Grimm (Jamie Bell) with powers they must learn to live with. "I'm gonna need a heat-resistant workshop," Johnny Storm, a.k.a the Human Torch, tells his sister. "And a big ass sun roof."

The trailer also hints at a meddling, over-bearing government — "They’re dangerous and powerful, which makes them extremely valuable," says Tim Blake Nelson's character, Harvey Elder — as well as a look at the quartet's arch-nemesis, Dr. Doom (played by Toby Kebbell). "This is the end of your world," the metal-masked man says. "And the beginning of mine."

Fantastic Four was directed by Josh Trank and opens August 7th. The film will feature a score by Philip Glass – the legendary composer's first time working on a superhero film – along with Marco Beltrami.
